Parameter Declaration Data type Description
DirectionPositive OUT BOOL Status: Direction of rotation positive
n TRUE: Current direction of rotation is positive
n FALSE: Current direction of rotation is not positive
DirectionNega-
tive
OUT BOOL Status: Direction of rotation negative
n TRUE: Current direction of rotation is negative
n FALSE: Current direction of rotation is not negative
Axis IN-OUT UDT 879 Reference to the general axis data of the inverter drive
V1000 IN-OUT UDT 881 Reference to the user data of the inverter drive
AxisComData IN-OUT UDT 878 Reference to the communication data of the current slave
The values for Velocity, AccelerationTime and DecelerationTime must be specified in the
user units of the FB 881 - VMC_InitV1000_RTU. AccelerationTime or DecelerationTime
always refer to the time from standstill to the maximum set velocity or from the maximum
velocity to standstill.
The maximum velocity results from the formula
v
max
max. velocity in 1/s
f max. Output frequency (parameter E1-04)
p Number of motor poles (motor-dependent parameter E2-04, E4-04 or E5-04)
1.
Select ‘Project è Compile all’ and transfer the project into your CPU. You can find
more information on the transfer of your project in the online help of the SPEED7
Studio.
ð
You can take your application into operation now.
CAUTION!
Please always observe the safety instructions for your inverter
drive, especially during commissioning!
2. Bring your CPU into RUN and turn on your inverter drive.
ð
The FB 882 - VMC_AxisControlV1000_RTU is executed cyclically.
3. As soon as AxisReady = TRUE, you can use AxisEnable to enable the axis.
4. You now have the possibility to control your drive via its parameters and to check its
status.
